Enum GateBlock 

pub enum GateBlock {
    ChannelEdges {
        predecessor_channel: String,
    },
    WavePromotion {
        host_wave: u32,
        current_wave: u32,

Reason a host can’t be dispatched right now. Variants carry enough detail to render the log line + observability event without re- querying state. The legacy &Observed-shaped gate variants from v0.1 are not represented.

WavePromotion

host_wave: u32

current_wave: u32

HostUnstaged

Default-deny variant of the wave-promotion gate: the channel declares waves but this host is not listed in any of them. Pre-hardening this case silently passed (position(...) returns None → ?-early-return → gate returns None → host dispatches). That’s an operator misconfiguration (host should be in a wave; either an operator forgot to assign it, or a fleet-build bug dropped it). Default-deny prevents silent dispatch of an unstaged host.

Implementations

impl GateBlock

pub fn reason(&self) -> String

Short human-readable reason for log lines + telemetry payloads.

pub fn discriminator(&self) -> &'static str

Stable kebab-case discriminator for telemetry.

Trait Implementations

impl Clone for GateBlock

fn clone(&self) -> GateBlock

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GateBlock

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for GateBlock

fn eq(&self, other: &GateBlock) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
